ADJUSTING DEVICE FOR THROTTLE GOVERNORS.

Application filed November 26, 1919.

To all whom it may concern Be it known that I, OMER B. \VHISENAND, acitizen of the United States, residing at Indianapolis, in the county ofMarion and State of Indiana, have invented certain new and usefulImprovements in Adjusting De vices for Throttle Governors, of which thefollowing is a specification.

This invention relates to an adjusting device for throttle governors,and is especially adapted for throttle governors wherein an operatingplunger is acted upon by fluctuations in the current passing through asolenoid, and it is among the objects of this invention to devise agovernor of this type which can be readily adjusted to vary at will thevoltage generated by the system.

Throttle governors of the type to which this invention is applicable areso constructed that when the voltage in the generator, which is operatedby an engine, reaches a certain point the throttle valve is choked offso that the output of the generator is held at a predetermined voltage.It is often desirable that this voltage be readily changed or adjusted,and my present invention contemplates a simple means for accomplishingthis result.

In carrying the objects of my invention into elfect, I fix the solenoid.to a movable portion of the governor casing and provide means wherebythe solenoid may be shifted relatively to the plunger operating withinit, and means are provided for clamping the solenoid in any of itsadjusted positions to a fixed portion of the governor casing. I may, ifit is deemed desirable, calibrate the movable portion of the casing toindicate the voltage to which the governor is ad justed in its variouspositions.

Referring to the accompanying drawings forming a part hereof and inwhich similar reference characters denote similar parts,

Figure 1, represents an elevation of a throttle governor with myadjusting device attached, and

Figure 2, a sectional view taken transversely as indicated on the line22 of Figure 1, some parts being shown in elevation.

The casing 1 of the throttle governor is secured in any well knownmanner to the manifold pipe 2 in which the throttle valve of the engineis located, and has a down- Wardly extending sleeve 3. Within thespecification of Letters Patent.

Serial no. 340,931.

sleeve is a movable casing 4 having fixed within it the solenoid 5, thecasing being adapted to slide in the sleeve. Conductor leads 6 from thesolenoid are connected to a suitable portion of the dynamo load line. Athumb screw or slotted set screw 7 is fitted into a threaded portion 8of the sleeve 3 and is adapted to bear againstthe movable casing -twhich carries the solenoid, and holds it in adjusted positions. l/Vithinthe sole noid is the plunger 9 attached to the plunger rod 10 whichoperates the throttle valve and having a spring 11 operatively connectedtherewith, s shown and described in the co-pending application of Ira T.Swartz, Serial No. 338,751, filed November 17 1919, on electromagneticthrottle governor. I sometimes place the indicating marks 12 along themovable casing 4 for more easily determining the proper adjustment ofthe solenoid and its casing to produce a given voltage.

Although I have specifically described my invention including a thumbscrew threaded in the stationary portion of the casing, it is to beunderstood that equivalent devices may be substituted therefor, and thatvarious other changes may be made in the construction, all of which Iconsider to be within my invention.

Having thus fully described my said invention. what I claim as new anddesire to secure by Letters Patent, is:

1. A throttle governor comprising a casing, throttle governing meansincluding a plunger connected to said casing and to the throttle valveof an engine, a second casing slidably mounted in parts of the firstcasing, a solenoid mounted in the second casing,

, and means for adjusting said second casing for regulating the positionof said solenoid relatively to said plunger.

2. A throttle governor comprising a casing, throttle governing meansincluding a plunger connected to said casing and to the throttle valveof an engine, a solenoid, said plunger operating within said solenoid,said solenoid being fixed to a movable casing, a sleeve formed in saidgovernor casing to allow said movable casing to slide therein, and ascrew threaded in said sleeve adapted to clamp said movable casing inany desired position.

3. In a throttle governor a casing, a down:

said sleeve.

4. In a throttle governor a casing, a downvvardly extending sleeveformed thereon, a

movable casing having a solenoid fixed therein Within said sleeve, meansfor adjusting said movable casing relatively-to said sleeve, andindicating means for determining the proper adjustme n of-iseidsolenoid. v

In witness whereof, I have hereunto set "my liaind ar'idseal-='atIndianapolis; Incliana, 15 "this Q lth day of "November; A. *D.nineteen hundred and nineteen.
